> Another one on behalf of [~selinazh] and [~cdrome]. Following the example in [Apache Tez's {{MapProcessor}}|https://github.com/apache/tez/blob/247719d7314232f680f028f4e1a19370ffb7b1bb/tez-mapreduce/src/main/java/org/apache/tez/mapreduce/processor/map/MapProcessor.java#L88], {{TezProcessor}} ought to use {{ProgressHelper}} to report progress for a Tez task. As per [~kshukla]'s advice,
> {quote}
> Tez... provides {{getProgress()}} API for {{AbstractLogicalInput(s)}} which will give the correct progress value for a given Input. The TezProcessor(s) in Hive should use this to do something similar to what MapProcessor in Tez does today, which is use/override ProgressHelper to get the input progress and then set the progress on the processorContext.
> ...
> The default behavior of the ProgressHelper class sets the processor progress to be the average of progress values from all inputs.
> {quote}
> This code is -whacked from- *inspired by* {{MapProcessor}}'s use of {{ProgressHelper}}.
> (For my reference, YHIVE-978.)
